I'm a novice here, so feel free to decimate any thing that seems backwards to any of you.
First of all, if your batch size allows, CO2 is a natural by-product of primary fermentation. For me, I don't see how anyone could want to "squander" that free and natural carbonation. What I do is stick it into a cold environment. Yes, cold conditioning aids in the natural absorbtion of CO2 into liquids. So, into the fridge it goes. If your handy, figure a way to afix a pressure gauge to your primary fermeter (mine came equipped with one) you will see the psi on it. After placing it into the fridge, you will see the psi drop.
Take it out of the fridge after a few days, rack it if you want for clarification. Prepare for bottling in the mean time. Add corn sugar at bottling day and you should be just fine. I just experimented with a batch the did NOT include this cold conditioning, and it was flat man, I mean FLAT! Seconary for a little over a week, corn sugar at bottling. Sampled a bottle after about six days and I was very happy at the carb level.
had another batch in primary, finished the fermentation. had about 15 to 17 psi on the gauge, stuck it into the fridge, after three days, the gauge is at zero. Where is the CO2? Pulled a few ounces and what do you know? IT's In THE BEER!!
I still plan on racking to secondary for a few and then on bottling day fixing up som dextrose to add and I'll let you know.
As the crow flies, the bottle I opened tonight is still very green at one week. No head retention but mouth feel was very acceptable. Trust in time above all. I can imagine what this beer will be like in two or three more weeks.
Good Luck
